Question

I have these bits of code and I’ve been at it for hours but I cannot figure what is wrong.

I keep getting a 500 server response, and it wouldn’t even start debugging in the view definition when I trigger the ajax.

I’m really at a loss, any help would be fantastic!

    $('.cheque_info_edit_button').live('click', function(){

var new_cheque = {
    // cheque number is taken from the cell, not input box for this one.
    cheque_no: $(this).closest('td').closest('tr').find('.inv_prof_cheque_no').text(),
    their_bank: $(this).closest('td').closest('tr').find('.new_their_bank_input_ajax').val(),
    our_bank: $(this).closest('td').closest('tr').find('.new_our_bank_input_ajax').val(),
    cash_in_date: $(this).closest('td').closest('tr').find('.new_cash_in_date_input_ajax').val(),
    cheque_amount: $(this).closest('td').closest('tr').find('.new_cheque_amount_input_ajax').val(),
    info_type: 'edit'
   };

    var cheque_json = JSON.stringify(new_cheque);
    $.ajax({
       type: 'POST',
       url: '/best_choose/invoice/profile/inv_add_or_edit_cheque/',
       data: cheque_json,
       success: function(){
       // do stuff
}

UPDATE: I don’t think syntacticly there are anything wrong with my view, so I took it out and added the traceback, is it something wrong with the csrf token? All of my other ajax functions work

I saw ur jquery code and there should not be any errors…

just a wild guess because something similar happened to me before and took me a while to realize it (forgot what the traceback looks like)

You may want to check your urls file and make sure you’re not using the same url or the wildcard of an existing url pattern.
